P2840S-4N-E67 WKP35S — Drilling/Boring Indexable Insert, Tiger·tec Silver, for Steel & Cast Iron — Walter Tools

The P2840S-4N-E67 WKP35S is an indexable insert designed for drilling and boring, optimised to machine steels and cast irons with the Tiger·tec Silver coating family.

• Tiger·tec Silver coating for long tool life
• WKP35S coated carbide for steel and cast iron
• Stable chip formation under heavy cuts
• Optimised chipbreaker 4N-E67 for consistent results

Longer tool life through advanced coating and grade

The Tiger·tec Silver family and the WKP35S grade combine to deliver enhanced wear resistance and sustained cutting performance. The multi-layer coating reduces abrasive wear and thermal impact during intermittent drilling cycles, which translates into fewer tool changes and longer productive runtimes. In practical terms, this means more consistent component quality under repeated operations and reduced machine downtime. The insert’s coated carbide substrate supports stable edge retention, which helps maintain hole accuracy and surface finish during series production.

Broad material range for fewer tool variants

Engineered for the ISO groups P (steel) and K (cast iron), the geometry and chipbreaking features address the characteristic chip forms of each material family. For steels, the grade copes with typical heat generation and long continuous chips, while for cast iron the cutting edge and chipbreaker manage short, brittle chips and abrasive wear. This multi-material capability reduces the need for separate inserts for each workpiece type, simplifying tool inventory and enabling faster changeovers on mixed-production lines. The result is measurable productivity gains and a leaner tooling strategy.

Predictable chip control and process stability

The 4N‑E67 chipbreaker is optimised to produce predictable chip segmentation across varying feed rates, improving evacuation during deep drilling and boring. Predictable chip behaviour reduces the risk of rework, tool breakage and machine stoppages. Combined with the grade’s stable cutting edge, the insert contributes to reproducible hole quality and dimensional precision. For process engineers, this translates into easier parameter setting and a tighter tolerance window without extensive trial runs.
